Question

write down the formula to calculate average velocity?​

Answer 1

Answer:

Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two. Where: ¯v = average velocity.

Answer 2

Answer:

As the word states, Average Velocity is the average value of the known velocities. Average Velocity is defined as the total displacement travelled by the body in time t. The average velocity is denoted by Vav and can be determined using the following formula:

AverageVelocity=TotalDisplacementTotalTime

Based on the values given, the above formula can also be written as:

(i)If any distances xi and xf with their corresponding time intervals ti and tf are given we use the formula:

Average Velocity Formula -2

Where

xi = Initial Distance

xf =Final distance

ti = Initial time

tf = Final time

(ii)If final Velocity V and Initial velocity U are known, we make use of the formula:

Average Velocity Formula -3

Where,

U = Initial Velocity and

V = Final Velocity.

(iii)If there are diverse distances like d1, d2, d3 ……. dn for diverse time intervals t1, t2, t3,… tn then

Average Velocity Formula -4

Average Velocity Problem

Problem 1: A car is moving with an initial velocity of 30 m/s and it touches its destiny at 80 m/s. Calculate its average velocity.

Answer:

Given: Initial Velocity U = 30 m/s

Final velocity V = 80 m/s

Average Velocity Formula -3

Average velocity Vav = (30 + 80)/2

Average velocity Vav = 55 m/s
